A new calibration of the α Cen system is presented. It shows that a theoretical model consistent with the observations and with the higher masses determined by Pourbaix (1999) can be obtained. Our model of α Cen A has a convective core. This could serve as a discriminant in a future asteroseismological calibration of the system.
